### Auto Compact Feature
OpenCode includes an auto compact feature that automatically summarizes your conversation when it approaches the model's context window limit. When enabled (default setting), this feature:
- Monitors token usage during your conversation
- Automatically triggers summarization when usage reaches 95% of the model's context window
- Creates a new session with the summary, allowing you to continue your work without losing context
- Helps prevent "out of context" errors that can occur with long conversations
You can enable or disable this feature in your configuration file:
```json
{
"autoCompact": true // default is true
}
```
